UNITED STATES WM. W. MARSTON, OF NEW YORK, N. Y.

BOOK STAND OR HOLDER.

Specification forming part of Letters Patent No. 49,639, dated August 29, 1865.

To all 'whom it may Gomera:

Be it known that I, WILLIAM W. MARsToN, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Book-Holders or Adjustable Stands; and I do hereby declare the following to be a full, clear, and exaot description of the said invention, reference being had to the annexed drawngs, making part of this specification, wherein Figure lis an elevation representing the adjustable standard and a portion of the table for holding the book. Fig. 2 is a section through the book-table, representng also the standard and parts attached, and Fig. 3 is a plan of my improved holder.

Similar marhs of reference denote the same parts in all the figures.

The nature of iny said invention consists in a standard that may he attached to any part of a chair, table, or other article of furniture, either vertically, horizontally, or at an inclination, and carries an adjustable arm and segment, with a table or book-holder, in such a inanner that the table or book-holder can be raised or lowered or brought nearer to or moved farther from the person and placed either level or at an inclination, thus obtaining a universal book holder or stand.

In the drawings, a represents a portion of a chair-seat arm, table, or other article of furniture to which my iinprovement is at-tached.

b is a standard, with a foot, c,at its end, and a sliding clamp, d, upon a feather taking a slot at 1 in said standard, and e is a nut on a screw, Z, formed around said standard, whereby the clamp d is actuatcd so as to grasp the chairseat or other device to which the book-holder is attached. The surfaces of the clamps o d should be covered with leather, felt, or any suitable substance, so as not to injure the furniture to which it may be clamped, and the screw part on the standard Z) should be sufficiently long' to allow the necessary opening between c and d to grasp whatever size of article desired. The standard bis formed of a round parallel rod, so that the socket f may be placed at any point of its length and turned around on any side of said standard; and g is a clamping-sorew to hold the socket f at any desired position. The socket f has a hole through it at right angles, or nearly so, to the hole for the standard b, which second hole receives the'gudgeon of the arm h, which arm h sets at its side against a box or circular side, 2, to the socketf, which, in connection with the clamping-nut 3 at the end ofthe gudgeon ofsaid arm h, produces sufficient friction to hold the arm h in any position or at any angle at which it may be placed.

At the moving end of the arm h a segment, i, is attached, that is formed at the other end as an aro ot' a oircle at 4, setting under the edge of a clamping-block, 5, actuated by a screw, 6, and this segment i has a flange at right angles to its surface, or other device for attachng the table or book-holder lt. This table 70 may be of any desired Character or size. I have shown it formed with a ledge at the bottoni, and with springs to hold the book open, ot' the usual nature.

It will now be understood that, the arm h being adjustable on its gudgeon to any angle, the inclination of the table may be varied thereby, or it may be varied by loosening the clamp 6 and turning the segment or the book-holder' can be brought bodily nearer to or moved farther from the person by the joint action of the arm h and segment fi, as illustrated by the red lines in Fig. 2.

What 1 claim, and desire to secure by Letters Patent, is-

1. The socketf, in combination with the arm h, set on a gudgeon, and with the standard Z), the parts being constructed and employed substantially as specified.

2. The segment i, in combination with the arm h and standard b, substantially as and for the purposes specified.

In witness whereofI have hereunto set my signature this 17th day of July, 1865.

WT. VV. MARSTON.
